To all whom it may concern:

Be it known that l, CHARLES F. Knitwonrnr, a citizen of the United States, residing at Waterbury, in the county of New Haven and State ot Connecticut, have invented certain new and useful improve- :ments in Furnaces, of which the following isy a specification, reference being had to the accompanying drawings.

This invention relates to a new and improved furnace, and has particular reference to the means for loading and unloading the same.

-llt is the object ot my invention, amena other things, toA so design such loading and unloading mechanism that the load is automatically shifted from its receiving?,` position to a position wherein it is in line with the annealing chamber, and vice versa, and construct the several parts so that they may be economically produced and capable of withstanding rough, hard usage, without becoming disarranged or injured.

Tothese, and other ends, my invention consists in the furnace, having certain details ci: construction and combinations oil parte, as will be hereinafter described and more particularlypointed out in the claims.

Referring to the drawings, in which lilre numerals ot reference designate like parts in the several figures; Figure 1 is a sectional elevation ot rny improved furnace; Fig. 2 is an .enlarged fragmentary plan view oi the elevator mechanism; and Fig.' 3 is an enlarged transverse sectional elevation talren substantially upon line A-Bot Fig. 1 with the elevator in its down position.

ln the drawings l' have illustrated the preierred form o-rny improved mechanism, but any other form having the essentials ol my mechanism will operate equally as well.

As herein shown, the furnace has two tanks 1-1, of substantially the same size and shape, that are lled with water or other duid up to the line Q, and interposed i therebetween is a furnace 3, having an annealing chamber or retort l therein. f

, onnected with the furnace or retort, at opposite ends thereof, are the hoods 5, which are substantially one-halt the width of 'the tanks '1 -1, and project therein below the water line 2 so as to forni an air seal.

Projecting into the lower portion oi? the tanlrs 1 1, and below thesarne, are the cylinders 6, in which are operatively mounted the pistons 7. Alined to the top of these pis tons is a beam 8. having plates 9 thereon carrying grooved wheels 10 that engage guide bars il fixed to the inside of the tanks. The operative engagement oi these cirrooved wheels with the guide bars, prevents the rotation of the piston 7 and the parts connected therewith. Fixed to the beam 8 and projecting outwardly and upwardly upon opposite sides thereof at both ends, are the trunnion arms 12 and 13, having;T the recesses it in the upper ends thereof. The platform mechanism comprises the :trainee l5 that are secured together by rods 16, 1'? and 18, and

have a central opening i9 therein that termi' natos near the bottoni ot said trames; rollers rotatably mounted in the trames; and the stop arrns 2l dared upon one end of said iframes.

Tflithin each of the tanks l. there is secured the bracket 22, having a roll 23 rotatably mounted therein, which roll is in the path of the ends oir the trames l5 lor tilting` the elevator as hereinafter described.

"in Fig. d of the drawings, the elevator mechanism its down position, with the platform thereod tilted, is illustrated by lull lines, and its up position, with the elevater platiorro horinontal, broken lines. ln this latter position it will he observed that one Vside of the hood 5 below the water line 2 projects into the opening 119 oil the elevator :trainee l5, and that upon one side thereof is exposed above the top et the tanl: l, and upon the other side it is within the hood 5 and above the water line 2. Aurning the elevator to be in its up position, the load, represented by the hrolren lines 26, is placed upon the rollers exposed outside ot the hood 5 and above the tanlr 1. The elevator is then lowered below the water line, and when near the lirnit of its downward movement, the trainee l5 contact with the rolls 23 and cause the same to rockupon the rods lo within the recesses 1li of the trunnion arms 13, thereby tilting the plattorni. When the platform is in this position the load will shi-lt from. its original poside ol the platform h rollers 20 ifasitionA to the'opposite against the stop arms 2l, 't cilitating this movement.

now moved upwardly and the platform assumes its horizontal position when the rod is in a higgner horizontal than the rolls 23, at which tirne 'the rod l; and lie within recesses in the trunnion arms 12. ltthe completion the upward elevator is will enter thereof.

Stroke of the piston 7 the 10aa will be within the hood 5 above the water line 2 and opposite the annealing chamber 4. It is moved from the platform into the annealing chaming chamber 4, another load is placed upon that portion of the platform outside of ,the hood, as above described. The elevator mechanism for receiving the load aft-er it4 passes through the annealing chamber is'located at the opposite end of the annealing chamber and is of substantially the same construction as thatv above described, with the exception that the elevator is tilted in its downward movement in the. opposite direction, so that the load mav. be shifted from that portion of the platform operative in line with the hood to that portlon outside There are minor changes and alterations that can be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of my invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is i 1. In a mechanism of the character described, the combination with an annealing furnace; of delivery and discharge means therefor rovided with means for automatically shi ting the relative position of the load thereon between its receiving and its discharge positions.

2. In a mechanism of the character described, the combination with an annealing' furnace; of an elevator for receiving and delivering loads therein; means forY moving said' elevator; and a fixed part in the path of movement of said elevator, and engaged thereby, to shift the angular osition of a part ofsaid elevator during t e movement thereof.

3'. In a mechanism of the character described, the combination with an annealing furnace; of a non-rotatable elevator for receiving and discharging loads therein; a platformupon said elevator; andv means for moving said-platform from a substantially horizontal position to a position wherein it lies at an angle to its horizontal position.

4. An annealing furnace, comprising a retort, a hood inclosing an opening to said retort, a seal located adjacent to said hood and int^ which said hood extends; an elevator with a portion thereofmovable in line with said hood and a portion thereof movable in line outside of said hood; and means f for shifting a load upon said elevator from' that portion of'the platform 'outside of the hood to that ortion of the platform in line therewith an vice versa.'

5. In mechanism of the character described, the combination with a reciprocating frame; of means for fpreventing the rotation thereof; a plat orm; means for mounting ysaid platform upon said frame so that it may rock thereon in relation thereto upon two different axes; and a fixed member in the path of said platform that engages the same and =causes it to rock upon one of said axis during the movement of sa'ld frame.

In testimony whereof I aiiix my signature in presence 'of two wltnesses.
